EXADATA -- installing DST fixes for 2016

Recently installed DST patches to Exadata Cells, and I must say it is pretty straight forward.
The approach to be followed is no different than the action plan documented in "Exadata Instructions as Turkey Continues on Daylight Savings Time From 2016 (Doc ID 2195169.1)"
I have done this demo for making Exadata cells to be aligned with the recent Turkish DST rule change. ( Turkey decided to not to observer DST rules any more, Turkey decided to stay in ETC+3)

The most important thing to be done is to check the OS release of our Cells in order to decide the correct tzdata patches for our CELL OS nodes.

[root@osrvcel01 ~]# cat /etc/redhat-release

Red Hat Enterprise Linux Server release 5.5 (Tikanga)

It is also important to ensure the image version is up-to-date enough for updating the tzdata packages.Note : this approach is applicable for Oracle Exadata Storage Server Software between 11.2.2.4.2 to 12.1.2.3.3 , in short Release 11.2 to 12.1.
